What is Slope-Intercept Form?

What are Transformations?

• An operation that maps an original figure called the pre-image.

• An example of a nonrigid motion in that it does not deserve congruency.

• A flip over a line called the line of reflection.

• The line passes and the slope of the line. we can right the equation in point-slope form.

What is the slope-intercept equation?

• y= - 4/5x + 8

• y=  4/5x - 8

• y= - 5/4x + 8

• y= - 8x - 3

What is a Translation?

• Formed by negating the hypothesis and conclusion.

• A segment is a point that divides the segment into two congruent segments.

• A fixed point called the center of Rotations.

• Vertically and/or horizontally slide of figure.

How is trapezoid ABCD translated to trapezoid A'B'C'D'?

• Translated 5 units down and 5 units to the right

• Translated 5 units down and 1 to the right

• Translated 8 units down and 5 units to the right

• Translated 5 units down and 4 units to the right

What are Vectors?

• It is not this answer.

• A quantity with both direction and magnitude, or size.

• A nonrigid motion.

• The preimage of a point, then its image after a dilation centered at the origin.

A translation vector is a vector that gives the length and direction of a particular translation.

• True

• False
